Public bug reported:

Currently the config setting:
allow_resize_to_same_host

only mentions:
Allow destination machine to match source for resize. Useful when
testing in single-host environments. By default it is not allowed
to resize to the same host. Setting this option to true will add
the same host to the destination options.

However, this setting is NECESSARY to resize hosts in an affined server
group via ServerGroupAffinityFilter

and while this is a cosmetic setting, it is likely contributing extra
work to anyone who allows this filter and generally allows resizing.
This was tripped across when doing Trove testing (which allows affinity
or a-a for a db cluster.)

An issue (cosmetically) in at least Liberty through master (Ocata).
